It's said that many brain diseases, such as autism and Alzheimer's, will be looked at with a significant difference. The treatment and study of such diseases will be more advanced. It just goes to show that in the world of technology and understanding, including health science, the world is always changing. It never slows down. "The discovery was made possible by the work of Antoine Louveau, a postdoctoral fellow in Kipnis’ lab. The vessels were detected after Louveau developed a method to mount a mouse’s meninges – the membranes covering the brain – on a single slide so that they could be examined as a whole."
